TAPE-MOISTENING DEVICE.

Specification of Letters Patent.

Patented Eeb. 8, i916.

' Application led'January 20, 1915. Serial No. 3,297.

f provide novel means whereby the end of the tape will be elevated withrespect to the l moistening device, after a predetermined length ofthetape has been severed, the construction being such that the free end ofthe tape on thel roll will not adhere to the moistening roller, or beleft in a plasticV side walls 2, an end wall 3, an intermediatecondition unfit for further use. l Another object of the invention is toprovide in a device of the class described, a

single element which exercises three fund tions, to'wit', a means forlifting the end of the tape after a predetermined lengthhas been severedtherefrom; a means for guiding the tape while the tape is passing fromthe delivery mechanism to the moistening device; and a means forengaging the moistening roller,` thereby to spread the moistening liquidon the moistening roller and to cause surplus liquid to flow back intothe tank. l s

Another object of the invention is to provide a novel form of brakemechanism which, coperating with ythe roll of tape, renders the tapeelficient as a means for depressinga resilient member, so that theresilient member` will engage the moistening roller, and so thatthe'tape mayr pass readily into coacting relation with respect to themoistening roller. l

1t is within the scope of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view which` will appear as thedescription proceeds, the inventionv resides inthe combination andarrangement of parts and in the details lof construction hereinafterdescribed and claimed, it being understood that changes, in thepreciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from Athe spirit of theinvention. Y

In the accompanying drawings z-Figure l shows the invention'in sideelevation; Fig.

`2 is a top plan wherein sundry parts have been broken away; Fig. 3 is avertical. lon gitudinal section showing the parts in the vpositionswhich they will assume while the tape is being advanced and moistened;Fig. 4C is a fragmental vertical longitudinal section similar to Fig.showing certain of the parts in the positions whih they will l sumeafter the tape has been torn cti the cutter; Fig. 5 is a verticaltransverse section taken through the tape delivery mechani'sm.

vIn t carrying out the present invention l there is provided asupportingstructure which is denoted generally by the numeral l. Thesupporting structure l comprises wall l: anda bottom 5, 'the end wall 3,the intermediate Walle, the bottom 5 and the side walls 2 coperating todefine at one end of the supporting structure, 'a tank 5 adapted toreceive water or ther liquid whereby the tape is moistened. At the rearend of the supporting structure l, the side "walls 2 are connected by anupstanding stop strip 7, the functions of which will be made manifesthereinafter. The side walls 9- are A'cured to the shaft 10 are spaceddisks l2 surrounded by a cylindrical shell 141. rEhe shell 14 may besecured to the disks `l2 or it may rotate thereon..

A cutter is employed for severing the tape7 the cutter in the presentinstance being shown in the-form of a strip or bar l5 extended acrossthe supporting structure l. and connected with 'the side walls Q. bymeans of securing elements 16. The cutter 15 is located slightly to therear of the roller 9 and is disposed in approximately horizontalrelation with respect to the upper portion of the roller. The side walls2 are united, to the rear of the intermediate wall 4 by af cross pin 17.The invention includes a forwardly' and upwardly curvedyieldable,tapeengaging member in the form of a spring tongue 18 whichmay be fashioned into an eye 19 engaging the cross pin 17 one "stoodclearly from Fig. 4. Disposed to the I' from Fig. 5. The tape which isto 30 rear of the spring tongue 18 is a guide roller 22 which may becarried .by a shaft -23 jour- -naled in or supported by the side walls2.

The invention comprises a tappe delivery mechanism, the same including ashaft 24 having reduced trunnions 25 at its ends, the trunnions 25 beingjburnaled in notches 26 formed in theupper ends of the standards 8. Thereduced trunnions 25 define ,shoulvders 27 the shaft 24 which,coperating with the standards 8, prevent the shaft 24 from moving'endwise as will be apparent be mois-l tened ordinarily is sold in theform o f a roll 28 wrapped about a core 30. The'shaft'24 passes throughthe core 30. The free'end of the roll of tape is denoted by thenumeral'29. i

Loosely mounted on the shaft 24 are disks v31, adapted-to'bearagainstopposite sides of the roll 28'oftape, the'construction -beingsuch that thev shaft may be vinserted readily into the disks'. The disks31 as shown best in Fig. 3, are provided with/ shoulders 32 adapted tocoact with the stop strip 7 to prevent the disks from rotating. Brakeelementsin the form of upwardly extended, resilient arms 33 .areprovided, the lower ends of the arms 33 being attached by means ofsecuring devices 34 to the inner y faces of the standards 8. The upperends l so positioned that theywill bear I upon the outer faces of thedisks 31, The l. In a tape mostener, a moistening 180 of the arms 33converge and are slotted as shown at 35 to receive the shaft 34, theupper vends of the arms 33 pressing yieldingly on the outer faces of thedisks 31, thereby to compel the disks to exert a retaining and brakingpressure on'the roll 28 of tape.

In preparing the machine herein disclosed .for use, the shaft 24 isinserted through the disks 31 and through the core 30, the roll A28 oftape thus being disposed between the disks 31. The arms 33 are spreadapart, the disks 31 and the roll 128 of tapeI are inserted -between thearms 33, 'and the trunnions 25 on the shaft 24 are inserted lintonotches 26 in the standards 8i Thus the roll oftape is supported forrotation, and the arms 33 are yieldingly free end 29 of the-roll 28 oftape is passed beneath the guide' roller'2`2, across the top free end 29of the strip of 4, the free end of the tape passing across the top ofthe moisteningrollerQ with obvious results. While the tape is beingdrawn out, the free, upper end of the spring arm 18 is swung downwardly,4as shown at F ig.' 3. This downward movement of the free upper end ofthe tongue 18 is. brought about for two purposes. First, in order thatthe free end 29 of the tape may'engage withthe moistening roller 9; andsecondly, in` order ythat the free upper end of the spring tongue 18 maylbear'upon the periphery of the roller 9, as shown in Fig. 3. When thefree upper end of the tongue 18 bearson the roller 9 as shown in Fig. 3,thewater on the roller is distributed, and at the same time, thevsurplus water on' the roller is compelled to pass backwardly into thetank 6, thus preventingl the tape from being moistened to too great anextent.

In connection with the spring tongue 18 when the tape is disposedadjacent the roller 9 as shown in. Fig. 3, it is to'be -observed thatthe disks 31 andthe brake arms 33 exercise .an important function, sincethey retard the tape enough so that the latter,

.when pulled'upon, will depressthe spring tongue 18 into the positionshown in Fig. 3..

When a sulicient length'. of tape has been unreeled, the tape is tornoff across'the cutter 15. So soon as this cutting off of the tape hasbeen effected, the spring arm 18 moves into the position shown in Fig.l4and elevates thev end of the roll of tape, so that the said end cannotcome into contact with the moistening roller 9. Consequently, after thetape has-been severed, the end of the roll of tape does not adhere tothe roller 9 and the end of the tapeon the roll isnot left in a moistand sticky condition, to adand stickycondition, so imuch'of the tape ashas been moistened, is generally torn oli and wasted, since it ismanifestly impracticable to'operate the machine properly and to applythe severed length of tape with` advantage, if the free extremity of thetape leading from the roll remains moist andA sticky as a result of apreceding operation. Having thus described theinvention, what is claimedis 4 acting member 'roller while the tane is being' neath the cutter tobind the 'tape against the cutter andto lift the end of the tape withrespect to the moieteningi means after the tape has been severed by thecutter, the cutter coacting ivith the resilient means to limit thelifting movement thereof.
